Fix strick-aliasing compiler warnings

When busybox is compiled (with gcc 4.4.3), there are thousands of
compiler warnings about code that is breaking the strict aliasing
rules that must be followed if -O2 or greater optimization level is to
be used.

Adding -fno-strict-aliasing to CFLAGS fixes this problem.

Patch is attached.
